i'm looking to purchase a late model K5 Blazer (1973-75) , and a buddy of mine suggested this board as a good place to try for advice. i have a few questions that i was hoping someone could answer, and feel free to point out anything i missed. 1. is there any reason i shouldn't look at the 73-75 k5? 2. how can i determine what a good price is for one, KBB only goes back to 1985, and i'm not sure where else to look. 3. should i go for one that has original parts, or look for rebuilt motors, trannies, etc. ? 4. i assume that there is an abundance of parts, so anything that is busted should be easy to get right? 5. how does one "check out" a 30 year old truck before purchase? i assume the standard things like no rust, straight body, etc. but what else? so far i've found 5 in the truck trader / on the web, and the median price for a 73-75 seems to be around $5k. understanding that any truck this old will require signinfcant work, i'm trying to come in under that. can you suggest any web sites that i can go to that i can start reading about the trucks, and learn some of this stuff up front? f i read it correctly, the 74/75 added full time 4wd, auto locking hubs, some other body / interior options, a new 4 barrel option for the 350 in 74, and with the 75 a new 400 ci v8 with a 4 barrel. so a few further clarifications on these changes. - how do people feel about the changes in the 4wd system? - i want an AT, are their any issues with the hydro matic? - my guess is that it doesn't matter which motor i get (preference is the 350 on the 73, 4 brrl 350 on 74, and 4 brrl 400 on 75) as this will be rebuilt either way, right? - air conditioning, i want this in the truck, but if it doesn't have it, it can be added later?
